* debian/patches/ppd-list-extract-also-arrays.patch: When polling a list of available PPDs/drivers from CUPS also read out data arrays from the IPP reply and not only the first values. Especially the info of all "*Product:" lines and of all supported languages of PPDs get available this way. To keep backwards-compatibility, the full arrays are in new fields in the output dictionaries, named as the old fields suffixed by "-all", like "ppd-product-all". * debian/rules: Added patch support.
